CIPHER CUT-OUT FOR ADDING-MACHINES.

Application filed April 24, 1907.

To all whom it may concern:

Be it known that I, CHARLES P. \Vnraronn, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Cipher Cut-Outs for Adding-Machines, of which the following is a specification.

My invention relates to printing adding machines, and the particular embodiment of it here shownis indicated as applied to the printing adding machine commonly known as the Comptograph, and generally shown in the various United States patents heretofore issued to Dorr E. Felt for printing adding machines and their mechanism, and more particularly shown in the patent to Felt and Vetmore, No. 853,543, issued May 14, 1907-; and the object of my invention is to provide mechanism whereby the automatic filling in of the ciphers to the right of any digit printed may be optionally prevented to the right of an order, to the-end that the operator may at will divide the listing into separate parallel columns that may be printed simultaneously without lateral shifting of the paper in the machine.

eating the tips of the sixth, seventh and elghth tail-piece levers 20 as partly set forward toward operative engagement with their u bars; and Fig. 9 is a partial sectional view lengthwise through the machine, to show the general relations of the adding and printing mechanisms.

Like reference numerals indicate like parts in all of the figures.

For each of the nine or more orders in the machine, there is a type segment bearing the 4t 0 77, 1779 C 2 7), 6 3 77 4C 4 777 4 5 77 6, 7, 8, 9, and presenting the zero at the printing line when in normal position. "When any one of the significant digits is to be printed by any type segment, suchtype segment is swung up to proper position to bring such digit type to the prlnting line. The same movement that operates to so position any type segment also operates to slightly set forward the corresponding tail-piece lever 20, so that in the subsequent completion of the printing action movement of the machine, such tail-piece lever will be engaged and moved farther forward by the movable member whose function it is to so engage and move the tailpiece levers that have been set as aforesaid, as set forth in lines 14rto 127 of page 5 of the patent to Felt No. 644,287 of February 27, 1900. Thus, in each complete operating action of'the machine, only those tail-piece levers are thrown forward which correspond to type segments that have been positioned to print significant digits, the other tail-piece levers remaining stationary. When any tail-piece lever is thrown completely forward, it engages one or more of the U- bars 21, and any U-bar so engaged is thrown forward far enough to strike against and trip the one or more hammer-pawls 22 with which the other arm of such U-bar is adapted to engage. The patent to Felt No. 644,287, on page 5 of the specification, sets forth the general operation of these U-bars, which are called releasing-frames in said patent.

The tripping of any hammer-pawl 22 releases the corresponding springactuated type-hammer 2%, and, of course, results in the making of a typeimpression in the corresponding order[ If a significant type has been set in position in such order, the type impression made will, of course, be a significant digit, but if the type segment in such order has not been moved from normal position, the type impression made will be the zero normally presented at the printing line by each type segment.

To the end that the aforesaid actuation of any U-bar to cause the printing of a significant digit may at the same time trip all the hammers of lower order that are not simultaneously actuated by other U-bars,- so that-a cipher may be printed in each lower order where no significant digit appears,' the ends of the forward arms of the U-bars are so notched that each U-bar, from that of the second order up, will engage not only the hammer-pawl of corresponding order, but also directly engage one or more ha1nmer-pawls of next lower order or orders, with the exception to be later explained. Thus, the U-bar of lowest order is so notched that its projection engages the extreme right-hand, or lowest order, hammer-pawl, and the iJ-bar of} second order 1S so notched that its projection 25, engages the hammerpawls of both the first and second order, and the third U-bar is so notched that its projection: 27, engages the hammer-pawls of first, second and third order, and the fourth ill-bar is so notched that its projection 28, engages the four right hand hammer-pawls, and the fifth U-bar is so notched that its projection 29, engages the hammer-pawls of the lowest five orders. And if this system of. notching were continued throughout the en: tire series of U-bars, each one of the U-bars of still higher order would in like manner engage with all the hammer-pawls of all the lower orders; but at the U-b-ar of sixth order, the drawings show a break in this progressive system of notching, and it will be noted that the U-bar of sixth order is so notched that its projection 30, engages the hammer-pawl of the sixth order only, and then the progressive system of notching is continued through the still higher U-bars, the seventh J-bar being so notched that its projection 31, engages the sixth as well as I the seventh hammer-pawl, and the eighth U- bar being so notched that its projection 32,

engages the sixth, seventh and eighth hammer-p awls.

The hammer face of the eighth order is set up, inasmuch as no cipher is present onthe ninth type segment, or ever required to be printed in the ninth or highest place.-

The above described break between the fifth and sixth orders, in the progressive is below the sixth order will always not.

system of notching of the U-bars, obviously provides that the actuation of any ill-bar only the hammer-pawl of corresponding order but also all the hammer-pawls of the lower orders, and that each U-bar above the sixth order trips both its corresponding hammer-pawl and the hammenpawls of lower order down to and including the sixth, but the actuation of the sixth or any higher U-bar would not cause the tripping of any hammers below the sixth order unless the sixth U-bar were in some manner coupled to and caused to actuate the U-bar of the fifth order. if such coupling is present and operative, it is obvious that the machine will be provided with a complete system of automatic cipher printing, so that the printing of a significant digit in any order will cause the filling in of ciphers in all lower orders in which significant digits are not simultaneously printed; but if such coupling, of the sixth to the fifth U-bar, is not effected, the

automatic cipher printing will be interrupted and cut out below the sixth order and the printing of a significant digit in the sixth or any higher order will not cause the filling in of any ciphers below the sixth order. Such a'coupling device, to couple the sixth U-bar to the fifth, is provided, and is made operable at the will of the operator. One of the arms. of the fifth U-bar has riveted upon it a forwardly projecting hooked clip 33, and the downwardly bent free end of the said. clip 33 is adapted to be engaged by the forwardly projecting tip 34 of the movable clip 35 pivoted at 36 on the U-bar of the sixth order. This movable clip 35 has a forwardly projecting arm 37 slotted at 38; and to swing this movable clip upon its pivot, so as to move it either into or out of engagement with the hooked clip 33, there is provided a sliding rod 39 having the downwardly projecting pin a0 engaged in the slot 38 of the clip-arm 37, The said sliding rod is moved back and forth by means of a thumb-khob ll, and is held in either of its detent 4 2 acting in the notches 43 of the block 44; carried on said sliding rod. When the said sliding rod is pushed in, the pivoted clip is swung to'the normal position shown in Figs. 1 and a, in engagement with the hooked clip 33, so that when the sixth U-bar, carryin said pivoted clip, is moved, it will carry with it and move to like extent the fifth U-bar; and when the sliding rod is drawn out, by pulling the thumb-knob, the

pivoted clip is ,moved out of dn'gagement with the hooked clip, and the sixth U-bar becomes free to move without in any manner affecting the fifth U-bar. It is thus evident that when the coupling device is in action, any actuation of the sixth U-bar will cause a corresponding movement of the fifth,

and so the printing of a significant digit in the sixth order would cause the automatn:

*dlin in of ciphers in all the lower orders a:

but it remains to rovide that the sixth U- bar, when thus coupled to the fifth, shall always be moved when any U-bar of still higher order, as the seventh or the eighth, is actuated, so that the same complete automatic cipher printing, in the five lowest orders, may take place when a digit is printed in the seventh or a higher order instead of the sixth. To effect this latter result, the ends of the other or rear arms of the U-bars and the tail-piece lever-ends engaging therewith are so arranged that the tail-piece lever of each order higher than 3 the sixth shall overlap and engage with not only the U-bar end of its own order, but also the ends of all the U-bars of lower order down to and including the sixth. Thus, the tail-piece lever-end 45 engages with only the end of the sixth U-bar, but the tail-piece levcr-end 46 of the seventh order overlaps the end of the U-bar of the sixth order as well as the U-bar of the seventh order, and

the tail-piece lever-end 47 of theeighth order overlaps both the U-bar ends of the sixth and seventh orders as well as the eighth order,so that the actuation of a tailpiece lever in any order above the sixth, will cause the actuation of the U-bar of the sixth order as well as the actuation of the U-bar of corresponding order, and the movement of the sixth U-bar will cause the movement of the fifth U bar, as aforesaid, if the coupling device is in action. It may be noted that the tail-piece lever-ends of the first, second, third, fourth and fifth orders each overlap not only the U-bars of corresponding order, but also some or all of the U- bars of lower order, but this has to do primarily 'with other considerations not directly involved in the cipher cut-out function of the device herein described, such over lapping merely effecting some distribution, among a plurality of the fibers, of the strain of tripping a plurality of the hammer pawls, inasmuch as without such overlapping a single one of thedJ-bars may sometimes have to take all of the strain of tripping a plurality of pawls. The position at which the coupling device is shown as located i the drawings, between the sixth'and fifth orders, would effeet the necessary cipher cut-out to enable the operator to divide the listing into two so arate columns one com risin the first 7 sitioned, and the U-bar notching and tail-v or right hand five places in the machine, and the other comprising the remaining or four left-hand places in the machine; but, of course, the coupler may be elsewhere popiece lever arrangement correspondingly modified, to effect the division of the listing between any other two columns.

adding-levers 48 performs the three-fold function of rotating the corresponding adding wheel 49, by means of the segment gear 50, of setting in position the type segment 51, by-means of the connection 52, and of setting forward the tail-piece levers 20 so that their curved slots 53 will be engaged by the comb piece 54 when the latter is subsequently rocked downward. (The patent to Felt, No. 644,287, on page 5 of the specification sets forth the manner of operation of this comb-piece or cross-bar). The movement of the aforesaid main-lever 48 is effected through the main-lever connection 55 that is pivoted upon said main-lever at 56. This main-lever connection is provided at its upper end with a cam-arm 57, adapted to be in constant contact with and shifted by the cam-stud 58 on the sliding cam-bar 59, which latter is shifted to greater or less of the keys 60, each of said keys being ar- I ranged to impinge against and shift one of the series of cams 61 that project upward from and are integral with the aforesaid sliding cam-bar. The extent of the movement of the cam-bar is thus determined by the key that is depressed, and in turn determines the extent to which the cam-stud 58 shall swing back the cam-arm 57 of the pivoted mainlever connection 55; and the extent to which the said short or cam-arm of the connection is swung back determines the extent to which the long or lower arm of said pivoted connection shall be swung forward. The extreme free end of said long arm of said connection 55 carries the stud 62, and the extent to which said long arm is swung forward determines the engagement of said stud in one or another of the series of notches G3 in the forward end of the adding arm 64 when the latter is rocked downward in the subsequent actuation of And the particular notch in which the aforesaid stud happens to engage, of course, determines the extent to which the main-lever 48 will be pulled down by its connection 55, upon the aforesaid rocking of the adding-arm 64. The adding-arm is secured to the main rock-shaft piece 65 and the rocking of said rock-shaft piece, upon the pulling of the operating handle of the machine, effects the movement of the adding-wheels and the positioning of the type-segments to the extent predetermined by the depression of the corresponding keys.

66 is the numeral Wheel stop that checks the forward movement of the numeral wheel effected by the segment gear 50, said stop being actuated through the connection rod 6? whose lower end is pivotally secured to I the forward end of the adding-arm.

The numeral Wheel mechanism is of course duplicated as many times as there are orders in the machine.
